Abstract
A base station can observe downlink communications of neighboring base stations of neighboring cells to determine operational parameters of these neighboring base stations in a process called sniffing. The base station ceases downlink transmission and/or uplink reception and initiates downlink reception for a duration in time and/or over frequency to form a sniffing window to observe the downlink communications of the one or more neighboring base stations. The sniffing window represents an area in time and/or frequency where downlink communications are not transmitted. The base station determines operational parameters based upon the downlink communications of the one or more neighboring base stations that are observed during the sniffing window. The base station and/or the one or more neighboring base stations can adjust their respective operational parameters such that, on average, each of the base stations within the cellular network should have a substantially similar deviation in their operational parameters.
